Performance Impact of Base Station Antenna Heights in Dense Cellular Networks

Optimal Base Station Antenna Downtilt in Downlink Cellular Networks

From very recent studies, the area spectral efficiency (ASE) performance of downlink (DL) cellular networks will continuously decrease and finally to zero with the network densification in a fully loaded ultra-dense network (UDN) when the absolute height difference between a base station (BS) antenna and a user equipment (UE) antenna is larger than zero, which is referred as the ASE Crash. We r...

Impact of the Base Station Antenna Beamwidth on Capacity in WCDMA Cellular Networks

In this paper the impact of the base station antenna horizontal beamwidth on radio network capacity in WCDMA cellular networks in the downlink direction is studied. Influence of coverage overlapping and radio propagation environment together with antenna beamwidth are also studied. A radio network planning tool is used to simulate WCDMA macro cellular network performance in urban and suburban a...

Base station antenna selection for LTE networks

Impact of base station antenna height and antenna tilt on performance of LTE systems

The impact of base station antenna height and antenna tilt on SINR in LTE systems have been discussed in this paper. Vienna LTE system level simulator has been used to obtain the results for studying the performance of LTE systems. Results highlight the point that changes in antenna height and tilt angle results in variations in the signal coverage and path loss of the network which in turn var...

A Base Station Smart Antenna System for CDMA Cellular

Adaptive antenna arrays can increase the capacity of wireless mobile communication systems by reducing cochannel interference. This thesis reviews current base station technology and examines the possibility of implementing an adaptive phased antenna array at a cellular CDMA base station. It is seen that a computationally simple beamforming system and direction-of-arrival estimator can signific...
